CENTRIFUGAL CREAM-SEPARATOR,

SPECIFICATION forming part of Letters Patent No. 593,032, dated November2, 1897.

Application filed June 16, 1897. Serial No. 640,975. (No model.)

To a/ZZ whom, it may concern,.-

Beit known that I, ERIK Gus'rnr NICOLAUs SALENIUS, a subject of the Kingof Sweden and Norway, and a resident of Kraftrilret, Albano, in theKingdom of Sweden, have invented certain new and useful Improvements inCentrifugal Separatore, of which the following is a specification.

This invention relates to that class of centrifugal separators whichhave within the drum for the purpose of increasing the skiinming powerof the apparatus various forms of partitions with their surfaces more orless inclined to the vertical axis of the drum; and the object of thepresent invention is to provide the drum with partitions havingadvantages over those heretofore employed and which are of annular formbent along one diameter and superposed in the drum.

In the accompanying drawings, which illustrate an embodiment of theinvention, Figure l is a vertical axial section of' the apparatus in theplane indicated by line 00' in Fig. 2. Fig. 2 is a horizontal section onthe plane indicated by line 0:2 in Fig. l. Fig. 3 is a side elevation ofthe cover G of the drum as seen from the right in Fig. l, the drum andupper casing being in section and the cover G broken away at the leftside. Fig. It is a side elevation, and Fig. 5 a plan, of one of theannular partitions detached.

A represents the drum of the separator, in the center of which ismounted the usual upright cylinder B, forming the milk inlet andreceiving chamber. This chamber has four equally-spaced radial outlets bb and b' b at its bottom. About the base of the central cylinder B is anannular support C for the annular partitions D. This support C, which isseen in plan in Fig. 2 and which may be separate from or integral withthe drum, as preferred, is inclined on its upper face oppositely from adiametrical ridge in order to properly receive and support thepartitions D. These latter are made of thin material and are circular,as seen in plan, Fig. 5, but angular as seen in side elevation, Figs. lvand 4;. If the partition D be cut in its annular form from anat sheet,the inner and outer contours will have to be slightly elliptical, so

that when bent along the shorter diameter to the angle seen in Fig. 4 itwill then be circular in plan. This is the construction seen in thedrawings, but it is not necessary that great care shali be exercised inthis respect.

lOn the partitions D are distancing cleats or devices d of some kind, sothat when superposed, as in Fig. l, there will be spaces betweenadjacent partitions. Each partition has notches d in its inner margin toreceive ribs b2 on the cylinder B when the partitions are in place.

The cover G rests on the pile of superposed partitions D to keep themdown in place and prevent them from becoming distorted in the operationof the apparatus. There may be, if desired, a plate F interposed betweenthe cover G and the upper partition. The cover G has a fiange g, whichrests on the upper margin of the drum A, and on it is supported a shellGX, the whole being held in place on the drum by suitable clamps H.

. Thel liquid to be separated (as milk, for eX- ample) is admittedthrough the cylinder B to the bottom of the drum and flows out at theradial outlets Z7 t1 and b Zi into the hollow of the annular support Cand thence back into the space inclosed by the partitions D. The outletsb deliver it at the sloping or inclined sides of the partitions and theoutlets b at the higher ridged sides thereof. The centrifu gal forcedrives the liquid outwardly between the partitions to the space betweenthe latter and the inner wall of the drum, and the heavier liquid thusseparated iiows upward through outlet tubes or channels I. (Seen inFigs. 1 and 3.)

The support C and partition D are herein shown as placed with theirupper faces inclining downward and outward from a diametrical ridge; butit will be obvious to any one skilled in the art that they may as wellbe inverted so as to incline upward and out- Ward.

Having thus described my invention, I claim* l. A centrifugal apparatushaving superposed in its drum a series of annular partitions D, bentangularly along one diameter only, said partitions being situatedsubstan- IOO tially concentric With the axis of the drum and separatedto permit the heavier liquid to pass outwardly between them.

2. A centrifugal apparatus having a drum, an upright cylinder at thecenter of said drum to form an inlet and receiving chamber for J[heliquid to be Separated, said chamber having oppositely-arranged radialoutlets at its bottom, and said apparatus having in its drumconcentrically arranged and superposed partitions, D, of annular formbent along one diameter only, as set forth, said partitions beingseparated to form spaces or passages for the outward ow of the heavier,separated liquid.
